3 Baseline Dual Speed Hub is an easy-to-use, 10/100
autosensing Class II hub (repeater). It is ideal for users who want to
connect both Ethernet and Fast Ethernet devices (workstations and other
equipment) to the same hub.
All ports on the Baseline Dual Speed Hub are half duplex, autosensing
10 Mbps and 100 Mbps. Each port senses the speed of the connected
equipment and operates at the appropriate speed.
The Baseline Dual Speed Hub comes with:
One power cord for use with the Baseline Dual Speed Hub
Four standard height, self-adhesive rubber pads
One rack mounting kit
A warranty information sheet with details of online registration
The Baseline Dual Speed Hub is suitable for office use where it can be free
standing or rack-mounted (in a wiring closet or equipment room). The
hub is powered from the AC mains supply
Network Connections
The Baseline Dual Speed Hub has 16 or 24 shielded RJ-45, 10/100
autosensing ports on the front panel. Each port can be connected to
either a 10BASE-T (Ethernet) or a 100BASE-TX (Fast Ethernet) device.
Internally, the hub has two repeater segments (10 Mbps and 100 Mbps)
which are linked by a switch, allowing connected 10 Mbps and 100 Mbps
devices to communicate.
You can connect a 10BASE-T or 100BASE-TX hub or switch to the
Baseline Dual Speed Hub.

MDI Switch
This switch affects port 16 (3C16410) or port 24 (3C16411). Ports 1–15
(3C16410) or 1–23 (3C16411) are fixed as MDIX ports. Each can be
connected to a device with an MDI port (such as most workstations) using
a normal “straight through” TP cable. Port 16 or 24 is “switch selectable”
using the MDI switch:
Out
In this position, port 16 or 24 is an MDIX port. It can be
connected to a device with an MDI port (such as most
workstations) using a normal “straight through” TP cable.
In this position, port 16 or 24 is an MDI port.
It can be connected to an MDIX port on a device (such as
another hub) using a normal “straight through” TP cable.

To connect the hub to a 10 Mbps or 100 Mbps unit, connect an MDIX
port on the unit to port 16 or 24 on the Hub. Ensure that the MDI switch
on the Hub is in (MDI). If an MDI/MDIX port is used on the other unit,
ensure that the MDI switch for that port is out (MDIX). Alternatively, you
can use “cross-over” TP cable to connect any MDIX port on the Baseline
Dual Speed Hub to any MDIX port on another unit.
Positioning the Baseline Dual Speed Hub
!
CAUTION:
When installing the Baseline Dual Speed Hub in a
stack of different size units, the Baseline Dual Speed Hub must
be installed above any larger units. Do not have a free standing
stack of more than six units.

Status LEDs
When deciding where to position the Baseline Dual Speed Hub ensure:
It is accessible and cables can be connected easily.
Cabling is away from:
■
The Status LEDs show the state of a port and whether or not the Link
Pulse signal is present on the segment connected to a port:
Green
Yellow
Flashing
Off
A 100 Mbps Link Pulse signal is being received and the
100BASE-TX segment attached to the port is functional.
A 10 Mbps Link Pulse signal is being received and the 10BASE-T
segment attached to the port is functional.
Packets are being received on the port.
The Link Pulse signal is not being received. Either nothing is
connected to the port, or there is a problem:
■
■
Sources of electrical noise such as radios, transmitters and broad-
band amplifiers.
Power lines and fluorescent lighting fixtures.
■
Water or moisture cannot enter the case of the unit.
Air flow around the unit and through the vents in the side of the case
is not restricted (3Com recommends that you provide a minimum of
25 mm (1 in.) clearance).
To prolong the operational life of your units:
Never stack units more than six high if free standing, and ensure that
cables are supported so that they do not cause the stack to fall over.
Do not place objects on top of any unit or stack.
Do not obstruct any vents at the sides of the case.
Check that the attached device is powered on.
Check that the cable is the correct type and is not faulty.
If the LED is off for port 16 or 24, check the setting of the MDI
switch. Refer to
2.
Try toggling the MDI switch.
If you have connected different types of unit together, check that
your configuration conforms to the network configuration rules
for 10BASE-T and 100BASE-TX.
If the port is connected to another unit’s MDI/MDIX port, check
the other unit’s MDI switch position.
Power Supply
Power problems can be the cause of serious failures and downtime in
your network. Ensure that the power input to your system is clean and
free from sags and surges to avoid unforeseen network outages. 3Com
recommends that you install power conditioning, especially in areas prone
to black outs, power dips and electrical storms.
The unit is intended to be grounded. Ensure it is connected to earth
ground during normal use. Installing proper grounding helps to avoid
damage from lightning and power surges.
If these checks do not identify the cause of a problem, it may be that the
unit or the device connected to the port is faulty. Contact your supplier
for further advice.
